NON-REFILLABLE BOTTLE Specification of Letters Patent.

Patented Jan. 23, 1906.

Application filed February l, 1905. Serial No. 243,666.

To all whom, t may concern:

Be it known that I, CHARLES L. E. WOLF, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Non- Refillable Bottles, of which the following is a specification.

The subject of the present invention is a bottle or similar receptacle which when once emptied cannot be relled, or at least will present such serious difficulties against refilling as to be practically non-refillable.

The type of construction in which my improvements are embodied comprises generally an annular seat within the bottle-neck, near the base of thelatter, and having a yielding bearing on a gasket supported on a shoulder at said base, a valve normally resting on and closing the seat, the valve being provided with vertical portions for guiding the valve in its opening and closing movements, a cylindrical plug being insertible through the bottle-mouth to occupy a position within the neck and be locked therein by movable means engaging shoulders within said neck, the plug being so conditioned that when inserted within the neck the lower end of the plug will primarily compress the gasket until the locking means has become engaged, whereupon the relative tendency of the gasket will cause the latter to coact in positively maintaining the locking means en aged. A gravity-sphere aids the reseating o the valve and normally contributes to hold said valve closed, besides presenting an interference with surreptitious attempts to refill the bottle by raising the valve through vacuum action. In the present improvements the valve, sphere, and interior of the plug are so arranged that the sphere, besides holding the valve to its seat by gravity, will form a positive locking medium for said valve against any attempt to lift the latter with a view of refilling the bottle, the construction, however, permitting the sphere when the bottle is tilted for pouring to assume a position whereby the valve can readily leave its seat to permit the liquid flow, which will not be objectionally impeded by the sphere. -The valve is of novel construction in that it possesses a rounded boss or protuberance on its top for coaction with the sphere in the valvelocking operation. Furthermore, the valve means external to the valve-seat and adapted to permit a free liquid flow when the valve is unseated will positively guide the valve in its movements, and thereby prevent unobjectionable tilting of said valve. The bottleneck has an annular clearance designed to cooperate with the baiiied passages in the plug to form part of the pouring-passage and also for aiding in venting the bottle during the pouring operation, so that an adequate and uniform liquid flow will be obtained. The

locking means which secure the plug against removal, and thereby prevent access to the sphere and valve, are in the form of dogs contained in recesses in the upper portion of the plug at the sides thereof, said dogs being designed to occupy a receded position within the recesses until the complete insertion of the plug permits said dogs to partake of a movement that will result in their becoming engaged beneath a shoulder within the neck to irmly lock the plug. These dogs are backed by cushionsections, which will be compressed when the dogs are in their receded positions, but which cushions will eX- pand to move said dogs to positively engage the same beneath the neck-shoulder. Oork will be highly advantageous for the cushions, as it will not only compress and expand, but will swell through moisture to aid in holding the dogs engaged.

In the drawings, Figure 1 is a vertical sectional view of the upper part of a bottle and illustrating my improvements, the valve being in the normallylocked position it occupies when the bottle is vertical. Fig. 2 is a view illustrating the position the parts assume when the bottle is tilted for pouring. Fig. 3 is an inverted sectional plan view of the plug in the plane indicated by the broken line 3 3, Fig. 1. Fig. 4 is a side view of the valve on an enlarged scale, and Fig. 5 is a bottom plan view of the valve on an enlarged scale.

The bottle-neck A contiguous to its mergence with the body A is contracted to provide an internal annular shoulder a, upon which is a yielding gasket d, preferably of cork. Supported on this gasket and of a diameter to snugly occupy the neck interior in a horizontal plane is a glass disk B, integrally having a depending flange making tight joint within the gasket. At its upper side the disk has a slightly-raised portion b', the periphery of which is threaded and contributes to form a shallow circular channel. Centrally on the portion b is a vertical annular seat b2, of integral character.

C refers to a plug which may be generally ICO IOS

IIO

of cylindrical configuration, according to the internal shape of the bottle-neck. This plug can be ol' about the proportions indicated and contains the upper longitudinal passage c and lateral baHling-passages c c:2 and inner passages, the latter' presented between the sides of short converging lugs or teeth C, arranged in a circular series, while the ends of said lugs at their lower sides conjointly form an interior circular clearance. The plug below the lugs Cf contains an ample chamber C2. The upper part o'l" the plug contains in its side surface recesses in which are located cork cushions d and movable dogs D. When the plug is inserted in position within the neck, the lower circular end of said plug is snugly received within the upper annular channel formed at the margin of the raised portion t of the disk B, the plug end being internally threaded to permit its positive engagement with the periphery of the raised portion b, said plug end also acting on the disk to compress the gasket c. The dogs occupy receded positions within their recesses to permit the inserting movement of the plug, the cushions d being compressed to permit the recession of the dogs. When the plug is completely in position, the dogs will have arrived opposite offset provision in the bOttleneck and the cushions will expand to cause the dogs to project and engage beneath shoulders a2, furnished by the o'l'liset provision, and thereby lock the plug in position, such locking being appreciably maintained by the reactive iniluence of the gasket a exerted at the lower end oi the plug, Previous, however, to such insertion and locking of the plug a sphere F and a valve E are placed in position in the plug-chamber C2 while the plug is inverted and the disk B adjusted at the end of the plug, so that the plug and parts carried thereby can be introduced and locked within the neck and the sphere coact with said valve and the series of lugs C, at the top of the chamber. The 4valve E is preferably of circular `form and adapted at its under side to rest air-tight on the seat t2, and for which purpose said valve may have a yielding disk e-say of cork-which can be snugly confined between vertical legs e of the valve. These legs are so disposed that lateral feet e2 will slidingly bear against the inner surface of the lower part of the plug, while spaced projections e3 on the valve correspondingly bear within said plug. The legs and projections serve to guide the valve in its movements relative to the seat an d prevent objectionable tilting of the valve. The latter has a centrally-located rounded protuberance eA1 at its upper side. /Vhen the bottle is in the vertical position, the sphere F bears on this protuberance and constitutes a lock for holding the valve to its seat. Upon tilting the bottle for pouring purposes the sphere acquires a position within the clearance provided by the lugs C at their inner ends, and the valve .E is thus permitted to be unseated by the liquid which flows through the seat-opening between the legs, thence between the sides of the lugs through the lateral bathing-passages c2 and a passage c3, presented by a rounded well A2 of the neck and connecting the passages c2 c', the liquid next ilowing through the passages c to the assage c and is discharged from the bottlemouth. The connecting-passage c3 aids in the venting of the bottle to promote an adeq uate and uniform flow of the liquid. Teats c4 c5 on the upper and lower sides of the partition coacting to form the passages c c2 c3 serve to strengthen said partition and also increase the diHiculty o'l inserting and attempting to manipulate awire in the plug. The lower teat will act as a stop for preventing the sphere from becoming tightly seated in the space presented by the lower ends of all the lugs C. As hereinbefore intimated, the engagement of the raised portion b of the disk with the corresponding threads in the lower end part of the plug enables allthe parts to be put together and positively connected before the insertion of the device within the bottle-neck.

The disk B, the plug C, valve E, and the sphere F will preferably be of glass, and therefore not subject to the deleterious effects of various liquids which the receptacle is designed to contain.

I do not wish to be understood as limiting myself` to the precise details and arrangement of parts shown and described, but reserve the right to all modi'cations Within the scope of my improvements.
